The PS2 OPTION for SP3 (A650-00) has the following two faults.
SYMPTOMS

2. New PS software cannot be reprogrammed into the PS2 board, because it is not
possible to erase the programmed software before reprogramming it.
CAUSES

the PC and the checker in the factory which downloads the software.

were used for the December production in 1997 and January production in 1998.
These chips cannot be erased before programming new software.
